Plastic to Oil Machine

Humans produce over 350 million metric tons of plastic waste annually. Without changes to current policies, this amount could triple to one billion metric tons by 2060. Even worse, these waste plastics take 10-1000 years to degrade, absorb toxins, and pollute the environment.

Currently, less than 10% of plastic waste is recycled per year. Most plastic waste generated is either landfilled (50%) or incinerated (10%), emitting harmful environmental pollutants. The remaining 30% is mismanaged or littered.

Burning/Incineration

• Environment pollution: Burning waste plastics releases around 850 million metric tons of greenhouse gases annually and may emit harmful chemicals.
• Not achieve resource recycling: Burning waste plastics creates non-reusable ash while producing new plastic consumes 8-10% of the world’s petroleum.

Landfill or Leaked into Oceans

• Land/Ocean pollution: Landfill occupies large amounts of land and pollute the soil. Leaking into oceans pollutes oceans and endangers the survival of marine life.
• Slow natural degradation: It takes 20- 500 years or more for a plastic bag to degrade in a landfill. It can’t meet the increasing need for plastic disposal.

Mechanical Recycling

• Limited recycling times: Plastics are not infinitely mechanically recyclable (washing, grinding, pelletizing, etc.). Most plastics can only be recycled 3 to 7 times.
• Reduced plastic quality: Recycled plastics may not perform as well as new ones, impacting market demand and the feasibility of large-scale recycling.

Plastic oil machine reduce plastic waste ton by tons. For the BLJ-16 model, it can reduce 4,380 to 5,840 tons of waste plastic annually.

Globally, 5 trillion disposable plastic bags are used every year, and these bags are produced using 60 million barrels of oil. Plastic to oil can save this consumption.

For example, with PE plastic (which has an oil yield rate of 90%), a BLJ-16 pyrolysis plant can recover approximately 3,942 to 5,256 tons of pyrolysis oil per year.

The process can also capture and reuse the gases generated, minimizing emissions. This reduces the carbon footprint associated with traditional plastic disposal methods like incineration or landfilling.

The oil produced can be refined and used in various manufacturing processes, including producing new plastics, promoting a sustainable recycling system.

This solution enhances the economic value of plastic waste, providing incentives for its collection and recycling. This helps to create a more sustainable and profitable recycling industry.

Feed plastic waste into plastic pyrolysis reactor. In the video, the batch plastic to oil machine adopts a hydraulic feeder. Remove the hydraulic feeder after feeding. The door must be closed and locked.

Start the main reactor rotation and preheating. Wait for the main furnace to reach the desired temperature. The fuel can be diesel, natural gas, heavy oil or pyrolysis oil. To save fuel consumption, we design syngas recycling.

When the main reactor’s temperature reaches about 100℃ after 2-3h, it begins to produce oil gas. The high-temperature flue gas generated during pyrolysis is heated in the jacket layer of the catalytic tower, and the oil gas passes through the catalytic tower.

Then high-temperature oil gas enters the vertical tube condenser, condenses into liquid oil, and enters the storage tank for storage. Non-condensable pyrolysis gas enters the water seal and is recycled for reactor heating. The excess pyrolysis gas enters the exhaust chamber for burning out.

Close the burners after the reaction. The main reactor and the draft fan still operate normally. After 7-8h of natural cooling, the slag can be discharged by auto screw discharger and water-cooling discharger.

The high-temperature flue gas from the catalytic tower mixes the high-temperature flue gas from the main reactor then enters the flue condenser for cooling treatment, and enters the spray tower for spraying dust removal, then discharged through the chimney to the atmosphere.

Using catalysts significantly reduces the wax content in the oil produced during the plastic pyrolysis process, resulting in a higher-quality end product. This means the oil is purer and performs better, making it suitable for a wider range of industrial applications.

With the reduction of wax in the pyrolysis oil, the risk of pipeline blockages is greatly minimized. This directly reduces downtime due to cleaning and maintenance, significantly lowering maintenance costs and improving operational efficiency.

Wax accumulation can not only cause pipeline blockages but also lead to increased internal pressure within the equipment, posing safety risks. The use of catalysts prevents this from occurring, ensuring stable and safe operation of the equipment and extending its lifespan.

The main furnace combined floating sealing technology uses carbon fiber + high-temperature soft filler combined sealing. Compared with the traditional graphene packing sealing technology, it has significant high-temperature resistance, corrosion resistance and wear resistance.

High-end exhaust gas treatment system, combined with the higher exhaust gas treatment and wastewater discharge requirements of European clients, can provide semi-dry or fully dry desulfurization, denitrification and de-dusting system to meet European emission standards.

Hot air heating method is safer, more uniform in heating, and more precise in temperature control. The most important thing is that waste heat can be recycled, energy saving and emission reduction can save 20-30 % of energy consumption.

If overpressure occurs in the main furnace, the safety valve will automatically activate to relieve pressure. This can ensure the safety of both the equipment and personnel.

Given the system overpressure and storage safety hazards caused by the surplus pyrolyzed gas produced by the main furnace, as well as the possibility of power outages and other emergencies during the operation of the equipment, a safe and highly automated torch system is provided as a safety emergency device.

Nitrogen system is optional. Nitrogen is introduced for replacement before ignition and slag discharge to prevent flash explosions in the main
furnace and ensure safe and stable operation of the plastic to oil plant.

Recommend PE, PP, PS, and more (please to oil yield chart). Avoid plastics with chlorine and oxygen content like PVC and PET, as they can pose hazards and have low oil yields.

To get a high oil yield, please use relatively lower high temperatures and a slow heating rate. To maximize gas yield, please keep the reactor at a relatively higher temperatures and a faster heating rate. Recommend intelligent control system.

Implement a distillation line to further refine and separate the pyrolysis oil into various fractions, which can improve the quality and yield of the final oil product.

Conduct regular maintenance and cleaning of pyrolysis equipment to prevent blockages and ensure the system operates at its optimal efficiency, thereby maximizing the oil yield.
